Description

Technical Field

[0001] This utility model relates to the field of lithium battery pack technology, and in particular to a stacking structure for a modular lithium battery pack. Background Technology

[0002] In today's society, lithium batteries have been widely used in many fields such as electric vehicles, energy storage systems, and portable electronic devices due to their significant advantages such as high energy density and long cycle life. To ensure the safety and stability of lithium batteries during use, multiple lithium batteries are usually combined together and placed in a specially designed protective case.

[0003] To better accommodate lithium battery packs and provide ample protective space, existing protective cases are often designed to be quite deep. Due to the depth of the protective case, the operator's hand space is limited, making it difficult to accurately control the placement and angle of the lithium battery. This not only increases the difficulty of operation but also makes it easy for the lithium battery to be bumped and damaged due to improper operation, thereby affecting the battery's performance and safety. Moreover, when connecting the battery inside the protective case, the obstructed view and narrow operating space make it difficult for the operator to clearly observe the internal situation, which greatly reduces operating efficiency, prolongs assembly time, and increases production costs. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a modular lithium battery pack stacking structure, which can reduce assembly time and production costs.

[0005] A modular lithium battery pack stacking structure according to an embodiment of the present invention includes:

[0006] A battery component, the battery component including a mounting cover and a battery pack, the battery pack being mounted on the inner surface of the mounting cover;

[0007] The pick-and-place component includes a support plate, a damping rod, a damping ring, a limiting plate, and partitions. The support plate is disposed on the lower part of the inner surface of the mounting cover. The damping rod is fixed to the inner surface of the mounting cover. The damping ring is fixed to the top of the support plate and the damping connection is on the outer surface of the damping rod. The limiting plate is fixed to the top of the damping rod, and the two partitions are fixed to the top of the support plate.

[0008] According to some embodiments of the present invention, the inner surface of the mounting cover is provided with sliding grooves on both sides, and the outer surface of the support plate is provided with sliders on both sides, the sliders being movably connected inside the sliding grooves.

[0009] According to some embodiments of the present invention, a fixing component is also included, which includes a vertical plate and a slot. The slot is opened at the top of the inner surface of the slide, and the vertical plate is fixed to the top of the slider and inserted into the slot.

[0010] According to some embodiments of the present invention, the fixing component further includes a support block, an insert plate, a handle, an extension block, and a positioning groove. The support block is fixed to the upper part of both sides of the outer surface of the mounting cover. The insert plate moves through the inside of the support plate. The extension block is fixed to one side of the outer surface of the insert plate. The handle is fixed to the middle of one side of the outer surface of the insert plate. The positioning groove is opened inside the upright plate. The insert plate is inserted and connected inside the positioning groove.

[0011] According to some embodiments of the present invention, an inner groove is provided on one side of the support block, and a limiting block is fixed on the other side of the outer surface of the insert plate, with the limiting block inserted and connected inside the inner groove.

[0012] According to some embodiments of the present invention, a limiting component is also included. The limiting component includes a pressure plate and a moving groove. The moving groove is opened inside the partition, and the pressure plate is movably connected inside the moving groove and fits against both sides of the outer surface of the battery pack.

[0013] According to some embodiments of the present invention, the limiting component further includes a side plate, an internal threaded ring, a handle, and a threaded rod. The side plate is fixed to the top of the pressure plate, the internal threaded ring is disposed at one end of the outer surface of the side plate, the threaded rod is threadedly connected to the middle of the internal threaded ring, and the handle is rotatably connected to the outer end of the threaded rod.

[0014] The present invention has the following beneficial effects:

[0015] This invention features a support plate, damping rod, damping ring, slider, and groove inside the mounting cover. When stacking and assembling battery packs, workers simply pull the damping ring upwards along the outer surface of the damping rod. As the damping ring moves upwards, the support plate, which was previously obscured, is fully exposed to the external environment. Workers can observe the top of the support plate, accurately determine the placement and angle of each battery pack, and ensure that the battery packs are stacked neatly and orderly. This avoids problems such as poor connection or structural instability caused by positional deviations. At the same time, the operating space is effectively increased. During the assembly process, the operator's hand movements are no longer restricted by the narrow space, allowing for more free operation. This reduces the risk of misoperation caused by insufficient operating space and lowers assembly time and production costs. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please see Figures 1-3 As shown, this utility model is a stacking structure of a modular lithium battery pack 101, comprising:

[0027] A battery component, the battery component including a mounting cover 100 and a battery pack 101, the battery pack 101 being mounted on the inner surface of the mounting cover 100;

[0028] The pick-and-place component includes a support plate 200, a damping rod 201, a damping ring 202, a limiting plate 203, and partitions 205. The support plate 200 is disposed on the lower part of the inner surface of the mounting cover 100. The damping rod 201 is fixed to the inner surface of the mounting cover 100. The damping ring 202 is fixed to the top of the support plate 200 and is damped to the outer surface of the damping rod 201. The limiting plate 203 is fixed to the top of the damping rod 201. The two partitions 205 are fixed to the top of the support plate 200.

[0029] When the battery pack 101 needs to be stacked and assembled, the staff only needs to pull the damping ring 202 upward along the outer surface of the damping rod 201. As the damping ring 202 moves upward, the support plate 200 that was originally covered by it will be fully exposed to the external environment. The staff can observe the situation on the top of the support plate 200 and accurately grasp the placement position and angle of each battery pack 101.

[0030] The inner surface of the mounting cover 100 is provided with grooves 204 on both sides, and the outer surface of the support plate 200 is provided with sliders 206 on both sides, and the sliders 206 are movably connected to the inside of the grooves 204.

[0031] When the damping ring 202 moves on the outer surface of the damping rod 201, the slider 206 moves simultaneously inside the groove 204, providing support.

[0032] It also includes a fixing component, which includes a vertical plate 306 and a slot 307. The slot 307 is opened at the top of the inner surface of the slide 204, and the vertical plate 306 is fixed to the top of the slider 206 and inserted into the slot 307.

[0033] After the support plate 200 moves to the upper part, the upright plate 306 will be inserted into the slot 307 to fix the position of the support plate 200.

[0034] The fixing components also include a support block 300, an insert plate 302, a handle 303, an extension block 305, and a positioning groove 308. The support block 300 is fixed to the upper part of both sides of the outer surface of the mounting cover 100. The insert plate 302 is movable inside the support plate 200. The extension block 305 is fixed to one side of the outer surface of the insert plate 302. The handle 303 is fixed to the middle of one side of the outer surface of the insert plate 302. The positioning groove 308 is opened inside the upright plate 306. The insert plate 302 is inserted and connected inside the positioning groove 308.

[0035] The insert plate 302 can extend inside the support block 300. After the upright plate 306 is fixed inside the slot 307, the insert plate 302 is pushed so that the insert plate 302 is fixed inside the positioning slot 308.

[0036] The support block 300 has an inner groove 301 on one side, and a limit block 304 is fixed on the other side of the outer surface of the insert plate 302. The limit block 304 is inserted into and connected to the inside of the inner groove 301.

[0037] When the insert plate 302 separates from the positioning groove 308, the limiting block 304 will extend into the interior of the inner groove 301, which can prevent the insert plate 302 from being pulled out.

[0038] Working principle: First, when stacking and assembling the battery packs 101, the operator simply pulls the damping ring 202 upwards along the outer surface of the damping rod 201. As the damping ring 202 moves upwards, the slider 206 simultaneously moves inside the slide groove 204, completely exposing the support plate 200 previously hidden. The upright plate 306 inserts into the slot 307. Then, the insert plate 302 is pushed, causing it to insert into the positioning groove 308, thus fixing the position of the support plate 200 after it is removed. The operator can observe the top of the support plate 200, accurately controlling the placement and angle of each battery pack 101, ensuring the battery packs 101 are stacked neatly and orderly. This avoids problems such as poor connection or structural instability caused by positional deviation. At the same time, the operating space is effectively increased. During the assembly process, the operator's hand movements are no longer restricted by the narrow space, and they can operate more freely, reducing the risk of misoperation caused by insufficient operating space, and reducing assembly time and production costs. After the battery pack 101 is assembled, the operator holds the handle 303 and pulls out the insert plate 302, which separates the insert plate 302 from the positioning groove 308. The limiting block 304 extends into the interior of the inner groove 301, which can prevent the insert plate 302 from being pulled out. Then, the damping ring 202 moves outside the damping rod 201 to move the support plate 200 to the lower part.

[0039] Please see Figure 1 , Figure 3 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The limiting component includes a pressure plate 400 and a moving groove 401. The moving groove 401 is opened inside the partition 205, and the pressure plate 400 is movably connected inside the moving groove 401 and fits against both sides of the outer surface of the battery pack 101.

[0041] The battery pack 101 is stacked on top of the support plate 200, and as the pressure plate 400 moves inside the moving slot 401, the pressure plate 400 presses against both sides of the battery pack 101 to limit its position.

[0042] The limiting component also includes a side plate 402, an internal threaded ring 403, a handle 404, and a threaded rod 405. The side plate 402 is fixed to the top of the pressure plate 400. The internal threaded ring 403 is disposed at one end of the outer surface of the side plate 402. The threaded rod 405 is threadedly connected to the middle part of the internal threaded ring 403. The handle 404 is rotatably connected to the outer end of the threaded rod 405.

[0043] Turning the handle 404 drives the threaded rod 405 to rotate, so that the threaded rod 405 is clamped on the outer surface of the partition 205, fixing the position of the pressure plate 400 after it has moved.

[0044] The working principle is as follows: First, after multiple battery packs 101 are neatly stacked on top of the support plate 200, the crucial step of limiting and fixing the battery packs 101 begins. On both sides of the device, movable grooves 401 are designed to allow the pressure plate 400 to move. This provides a track for the flexible movement of the pressure plate 400. The operator pushes the pressure plate 400, causing it to slide smoothly along the movable grooves 401 towards the battery packs 101. As the pressure plate 400 gradually approaches, it eventually presses precisely onto both sides of the battery packs 101. When the pressure plate 400 is accurately positioned… After reaching the predetermined position and completing the initial limiting of the battery pack 101, the operator holds the handle 404 and rotates it. The rotation of the handle 404 directly drives the threaded rod 405 connected to it to start rotating. Since the threaded rod 405 and the separator 205 adopt a threaded fit design, as the threaded rod 405 rotates, it will gradually approach the separator 205 and eventually be tightly clamped on the outer surface of the separator 205. This can continuously and stably limit the battery pack 101, providing a reliable guarantee for the safe operation of the battery pack 101.
